WEATHER-STRIP.

Specification of Letters Patent. Application filed April 12, 1913.

To all whom it may concern Be it known that I, WILLIAM H. a citizen of the United States, residing at Racine, in the county of Racine and State of Wisconsin, have invented new and useful Improvements in Weather-Strips, of which the following is a specification.

This invention has relation to weather strips and it consists in the novel features hereinafter described and claimed.

An object of the invention is to provide a strip of simple and cheap structure especially adapted to be used in conjunction with windows or doors arranged to swing inwardly with relationto their frames. The parts are so arranged that when the window is closed, the members constituting the strip bridge the spaces between the edges of the window sash and the frame and prevent the passage of air and moisture. These memhers are also so arranged as to direct the moisture away from the window sash so that it cannot accumulate and freeze and thereby interfere with the movement of the sash. With these objects in view the weather strip includes members fixed to the side of the sash and adapted to overlap the edge portions of members loosely mounted upon the window frame. When the sash is open, the members upon the frame may be moved in close proximity to the surfaces of the frame and therefore the presence of the said members upon the frame will not obstruct the window opening therein.

In the accompanying drawings-J igure 1 is a perspective View of a window sash and frame with the weather strip applied. Fig. 2 is a transverse sectional View of one form of the strip. Fig. 3 is a transverse sectional view of another form of strip.

The weather strip comprises strip members 1 which are secured in fixed position to the outer side of the sash in the vicinity of the edges thereof. The members 1 are provided with angularly disposed edge portions 2 and 3. The edge portion 3 lies in close contact with the outer surface of the sash and securing screws 4 pass transversely through the portions 3 and secure the members to the sash. The portions 2 of the members 1 are disposed at acute angles to the outer surface of the sash.

Strip members 5 are loosely secured by means of screws 6 to the sides of the window frame and may be swung into position parallel with the surfaces of the said sides MAnzoLr,

When the sash is closed in the window frame, the portions 2 overlap the inner portions of the members 5. At the top and sides of the frame, the portions 2 lie against the inner surfaces of the members 5 while at the sill or bottom of the frame, the portions 2 lie against the outer surfaces of the members 5. Clips 7 are secured to the outer side of the members 5 at the sill of the window frame and are adapted to lie over the outer surface of the portion 2 of the lowermost strip member 1. The end portions of the clips 7 project beyond the inner edge of the strip member 5 at the sill of the frame and consequently when the sash is closed in the frame, the lower edge of the portions 2 of the lowermost strip member 1 may be readily passed between the outer surface of the lowermost strip member 5 and the under surfaces of the clip members 7. Therefore when the sash is closed in the window frame, the overlapping strip members bridge the spaces between the edges of the sash and the surfaces of the frame and consequently they will prevent the passage of air through the said spaces and will also shed water or moisture which is also prevented from passing through the said spaces. By reason of the angular disposition of the strip members with relation to the sash and the frame when the sash is closed, the moisture is directed away from the sash and consequently it cannot freeze and interfere with the movement of the sash.

By reason of the fact that the strip members 5 are loosely connected with the sides and sill of the frame, the said members may be swung in close proximity to the said sides and sill when the sash is in a position and therefore they present no obstruction through the opening of the frame. vVhen the sash is in a closed position in the frame, the portions 2 of the strip members 1 hold the inner portions of the strip members 5 away from the sides of the frame and when the clips 7 are over the upper surface of the portions 2 of the lowermost strip member 1, the inner part of the lowermost strip member 5 is held up away from the sill and in close contact with the undersurface of the said portion 2.

Having described the invention'what is claimed is:

In combination with a frame and sash,

plane strips loosely mounted upon the sill and stiles of the frame; and strips having on the sill of the frame and engageahle with angularly disposed edge portions fixed t0 the strip at the lower portion of the sash the lower and side portions of the sash, the to ,hold' the last mentioned strips in close strips being so arranged that when the sash contact with each other. 15 5 is in a closed position in the frame the strips In testimony whereof I aflix my signature at the sides (pf thfe slash will overlap again? in presence of two witnesses. the inner si es 0 t e strips at tie Si es 0 e the frame and the strip at the lower WILLIAM MARZOLF' portion of the sash will overlap against Witnesses: 10 the outer side of the strip upon the sill WALTON H. MILLER,

of the frame, and clips carried by the strip PAUL E. TRUELSGH.
